The subject matter relates to flavoring with a composition of matter consisting essentially of a pyrazine derivative having the following formula: ##STR1## wherein (a) R.sup.1 is a methyl group and R.sup.2 is either an alkyl group having from 2 to 6 carbon atoms which can be branched at the chain end when said chain has 3 or 4 carbon atoms, or a vinyl, a thienyl-2 or a pyrryl-1 group; or (b) R.sup.1 is an ethyl group and R.sup.2 is an ethyl or a vinyl group.
本主题涉及使用由基本上由具有以下公式的
吡嗪衍
生物组成的物质进行调味:##STR1##其中(a)R.sup.1是甲基基团,R.sup.2是具有2到6个碳原子的烷基基团,当该链具有3或4个碳原子时,可以在链末端分支,或者是
乙烯基、
噻吩-2或
吡咯-1基团; 或(b)R.sup.1是乙基基团,R.sup.2是乙基或
乙烯基团。
